Abstract: A new data acquisition technology of high resolution DEM is presented. The terrestrial laserscanning (TLS) system is used to capture data of point clouds. A high resolution DEM is created by data processing. Then the registration error is evaluated. The practice of the TLS system has demonstrated that this new technique can be used in creating high resolution DEM of a small watershed.

Key words: 3D laser scanning , DEM , small watershed , point cloud
